A gender-selection technique is designed to increase the likelihood that a baby will be a girl. In the results of the gender-selection technique, 876 births consisted of 447 baby girls and 429 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 447 girls in 876 births. b. Find the probability of getting 447 or more girls in 876 births. If boys and girls are equally likely, is 447 girls in 876 births unusually high? c. Which probability is relevant for trying to determine whether the technique is effective: the result from part (a) or the result from part (b)? d. Based on the results, does it appear that the gender-selection technique is effective? a. The probability of getting exactly 447 girls in 876 births is (Round to four decimal places as needed.)

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 94 people in the 18-21 age bracket and finds that 80 of them respond and 14 refuse to respond. When 265 people in the 22-29 age bracket are contacted, 241 respond and 24 refuse to respond. Assume that 1 of the 359 people is randomly splected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respornd. Report the answer as a percent rounded to one decimal place accuracy.
